6 GENERAL SAFETY AND OPERATION SELECTION: Review the Selection Chart to find the performance range and pump model suited to your application requirements. Then review the Performance Curve Chart to verify the most efficient performance and inlet conditions required. INSTALLATION: These pumps may be installed in either a horizontal (most common) or vertical position (as installation requires). The following criteria should be considered to assure optimum performance: Proper alignment of plumbing Adequate line size to prevent starvation Rigid metal or plastic pipe or reinforced flexible plumbing to prevent collapsing lines Properly sealed connections to prevent air leaks Good filtration of the liquid to avoid abrasives and solids Foot valve may need to be installed at the inlet. OPERATION: The pump comes with a standard seal for fresh water or non harsh liquids. Excessive ph, high viscosity and abrasives will affect the life and performance of the pump. Special shaft seals are available for high temperature or chemical duty applications. Check with factory for high viscosity liquids. Make certain there is sufficient liquid supply to the pump before starting operation. MAINTENANCE: This is a low maintenance pump. The shaft seal and impeller are the primary service items. These can be easily replaced.. Remove the or hex head screws and slide the casing from the cover.. Remove the impeller bolt and gaskets then slide off impeller.. Carefully pry the casing cover away from the bracket.. Lay the cover on the work surface (large diameter up) and press out the shaft seal.. Turn the cover over on the work surface (small diameter up) and press the back half (stationary half) of the new shaft seal into position until completely seated in the chamber with the elastomer side down. CAUTION Exercise care when handling the shaft seal. It can be easily contaminated by improper handling and will not properly seal. Use the paper cover to press the seal into position and toss the cover when done. NOTE: If seal installation is tight, carefully apply a small amount of lubricant to the outer edge (non-chlorine dish soap). DO NOT USE OIL OR GREASE.. Align the cover with the holes on the bracket and press into position. 7. Slide the front half of the seal (rotating half) onto the shaft sleeve with the elastomer side out (carbon/ceramic surfaces mating). Then slide the seal spring and washer onto the shaft.. Hold the seal spring in place, and then place gasket on top of spring retainer. Slide the impeller into position until completely seated. NOTE: Use a screwdriver to hold the motor shaft stationary. 9. Install the impeller bolt and gasket onto the shaft and torque per chart. Rotate the impeller to assure proper alignment before installing the cover. NOTE: Apply loctite to the impeller bolt before installing.. Place the new O-Ring over the casing cover. Exercise caution not to cut or twist the O-Ring during installation.. Replace the casing cover. Align discharge port in the upward position, and then align mounting holes. Replace or lockwashers, nuts and hex head screws and torque per chart. PROBLEM No flow or low flow Leaking Noise Vibration TORQUE CHART Torque Size ft. lbs. in. lbs.
